Problems solved by technology

On the other hand, the output of the micro-electrolyzer is increased after being enlarged, but the electrolysis needs to be carried out at a certain temperature. If the temperature is not up to standard, it will directly affect the electrolysis efficiency.
Furthermore, in traditional photovoltaic power generation, in order to improve the efficiency of photovoltaic power generation, it is necessary to control the temperature of the photovoltaic panel, and reducing the temperature of the photovoltaic panel will also cause a certain amount of energy consumption

Description

technical field [0001] The invention belongs to the field of electrolytic hydrogen production, and in particular relates to a diaphragm-free micro-electrolyzer-photovoltaic hydrogen production system and method, in which electric energy generated by photovoltaics is electrolyzed to produce hydrogen through a diaphragm-free micro-electrolyzer. Background technique [0002] At present, photovoltaic power generation has become the most economical clean energy in the world, and its cost per unit of electricity continues to decline. The low cost of electricity per unit of photovoltaic power generation brings opportunities to reduce costs for hydrogen production from electrolyzed water. Then, using sufficient and economical photovoltaic power to split water to produce green hydrogen can continuously expand the application scale of green hydrogen and accelerate the realization of the goals of carbon reduction and decarbonization in countries around the world. The existing mainstrea...
